U. S. Army ERDC, ElectroTechCP, and the Structural Group: Electro-Osmotic Pulse Control of Moisture in Below-Grade Concrete Structures

EOP technology combines the novel application of an asymmetric, dual-polarity pulse and innovative ceramic-coated electrode materials. The basic research for optimizing the EOP process has led to significant advances in the field of electro-kinetics for systems containing multiple material interfaces. An ability to control seepage-related humidity permits mitigation of occupant health risks from mold, mildew, and bacteria, with associated health and lost work-time costs. A recent cost analysis for rehabilitating two identical basements at Fort Bragg, NC, using EOP and conventional methods, showed the cost of EOP to be $133/linear foot and the cost of conventional water intrusion rehabilitation to be $262/linear foot.

Zachry Construction: Zachry Construction Employment and Conference Center

Zachry Construction Corporation built a new conference and employment center using the U. S. Green Building Council (USBGC) Leadership in Energy and Environmental Design (LEED®) Program with the goal of becoming a community and national leader in LEED® construction. The center is the first in San Antonio, Texas, to obtain one of the highest certifications from the USBGC: a Gold rating, and is only the fifth Gold-certified LEED® building in Texas.

Vincent Hock

Vincent Hock was project manager for an inventive and innovative R&D project related to the fundamental properties of electro-osmosis in concrete in contact with soil and water interfaces. Ultimately this research led to development of a technology to control the movement of water through low-permeability porous media. This team is credited with advances in electro-osmotic pulse (EOP) and ceramic-coated anode technologies, used together in a novel process to prevent moisture seepage into enclosed spaces.
